the expanded primitive is not provided by your TeX engine, listofitems v1.63 cannot work: loading listofitems v1.61

Scenario

I am compiling a latex document from python 3.6 in Anaconda 4.8.2 on a Windows 10 Pro N device. To do so, I created a python 3.6 environment in Anaconda Prompt, installed miktex in anaconda with command:

conda install -c conda-forge miktex

And execute the following python code with:

def create_pdfV3(self, input_filename, output_filename):
        argList = [
            'pdflatex',   # Or maybe 'C:Program FilesMikTexmiktexbinlatex.exe
            '-output-format=pdf',
            '-job-name=' + output_filename,
            input_filename,
            '-enable-installer']
        print(f'argList={argList}')
        process = subprocess.Popen(argList)                

Which returns the following error:

(C:UserssomeuserAppDataRoamingMiKTeX2.9texlatexlistofitemslistofitems.sty
(C:UserssomeuserAppDataRoamingMiKTeX2.9texgenericlistofitemslistofitems.tex

! Package listofitems Error: the expanded primitive is not provided by your Te
X engine, listofitems v1.63 cannot work: loading listofitems v1.61.

See the listofitems package documentation for explanation.
Type  H <return>  for immediate help.
 ...

l.67    {input listofitemsold.texrelaxendinput}
                                                %
?

From what I understand from the answer in this question the error is caused because the TEX engine that is used to compile the main.tex is not updated to include the expanded primitive.

The version used for pdflatex as found by executing command pdflatex --version manually in the python 3.6 environment of Anaconda prompt, yields:

pdflatex --version

Question

How can switch the TEX engine to enable compiling with the expanded primitive?
